Is there such thing as a 5.1 PCMCIA Sound Card? I know that there are stereo sound cards for laptop that are available in PCMCIA, but I have a laptop that I use and have the 5.1 Klipsch speakers for my desktop that I would like to use with my laptop. Plugging in just the front speakers to the laptop is no problem, but that's only 2.1. I searched the net but didn't find anythin, I don't think there is one, but wanted to make sure.....
